Verifiable Credential SDK in Java

This SDK is for creating/verifying W3C Verifiable Credentials and Presentations. The behavior is compatible with the Typescript SDK written by DIF.

Features

• Creating/Verifying W3C Verifiable Credentials using JWT
• Creating/Verifying W3C Verifiable Presentation using JWT

Currently, only external proof using JWT is supported. The embedded proof, such as a Linked Data Signature, would be supported in the future.

For more details, please see Usages.

Installation

For Gradle:

repositories {
    maven {
        url = "https://maven.pkg.github.com/medibloc/vc-java"
        // GitHub Packages credentials
        credentials {
            username = System.getenv("GPR_USER")
            password = System.getenv("GPR_API_KEY")
        }
